As F1 moves into the summer break, Ferrari are firmly in the lead, and Mercedes must be feeling just a little worried.Their supremacy is definitely being threatened, and so the Belgian Grand Prix (Spa-Francorchamps) will be crucial for them if they are to win this years Constructors and drivers championships. Crucial for Ferrari as well. If Spa is famous for anything it's the unpredictable nature of the race, courtesy of the weather. Frequently one part of the track can be sunny and dry, whilst just round the corner it's raining, quite a challenge for drivers. But despite the difficulties, or maybe because of them, Spa is popular with drivers and fans alike. Spa started life running on public narrow roads, between three different villages, but by 1983 it had become, more or less, the track we know now. A mix of long straights and fast corners and the longest F1 circuit on the F1 calendar. Kimi Raikkonen has had four wins at Spa, and certainly has the car to do so again, but I can't really see that happening. His team mate however, with two wins at Spa, and who is hungry for the WDC, will present a very strong challenge. McLaren have had a lot of past success at Spa. So Alonso for the win. Well no. Whilst I think we are all glad to see some small improvement in Team McLaren, it has a long, long way to go before it wins races, going flat out through the Eau Rouge - Radillon sequence and still being in the race will be an achievement, although in fairness Alonso did finish in 6th positioning Hungary. This is a circuit where you don't have to qualify on pole to win the race, so we should see some overtaking. Hamilton take note, a poor qualifying will mean some real racing, which to be fair he seems to enjoy. Obviously the top three teams, Ferrari Mercedes and Red Bull should do well. This is almost Max Verstappens home race, so we should see a very orange crowd of fans, lets hope in his enthusiasm to impress he doesn't take out all three top teams.Danni Ricciardo is only 1 point ahead of Kimi Raikkonen as of now, and that could be a fight worth watching, if Kimi can be bothered. Force India, pretty in pink, are doing a steady job as the lead team of the mid-field, it would be good to see a more exciting driver in one of their seats IMO. After that it's a steep curve down to Williams and the Torro Rosso. Renault, Haas, McLaren and Sauber are all struggling for points. Sauber have only 5. But the fickle nature of the circuits weather may have the final say, just take a look at the first lap shunt in 1998, thirteen cars were involved in that, it was total chaos.
